What is the Full Form of ROM?

-
ROM Full Form is Read Only Memory. It is a computer storage medium or computer memory. ROM is used in systems to store programs that boot the system. ROM is an acronym for read only memory and usually contains information relating to the start up applications and it is no-volatile memory, which cannot be written into. On the other hand, RAM refers to random access memory, which is highly volatile temporary information that allows the CPU easy access to particular programs, while the computer is running.
Unlike main memory (RAM), ROM retains its contents even when the computer is turned off, that's why we call it nonvolatile memory. ROM are much slower than RAM memories, or The difference between RAM and ROM is that RAM is Random Access Memory that is the temporary memory that the computer uses to perform its functions while being used while ROM is the Read Only Memory. ROM is the data that is permanently written to a chip, that there is no way of overwriting.
RAM is a type of memory that can be accessed non-sequentially while ROM is a type of memory that is only read in typical operation. The other difference is that ROM is non-volatile while RAM is volatile. There images can only be extracted through the effective use of some special software and hardware instruments. ROM are also used in laser printers or calculators.

Types of ROM :-
  • Read Only Memory (ROM)
  • Erasable Programmable Read Only Memory (EPROM)
  • Electrically Erasable Read Only Memory (EEPROM)
  • Programmable Read Only Memory (PROM)

What is the Full Form of LASER?

-
LASER Full Form is  Light Amplification by Stimulated Emission of Radiation.    These radiations have very specific properties that they use in different types of applications.  It is used to build a wide range of electronic devices, including CD Rom, Bar Code Reader. The light emitted by these devices are thin and consistent.    It is a breed of cattle which was born in the French of Massif Central. These are a large breed, the number of women is 700 to 750 kg and 1.40 meters long. They have thick red or black coat thick, and long, purple-shaped, light colored horns and small percentages are born without natural beings. In the 19th century, breeder Ernest Tystader D'Vasas established breed by selective reproduction.  Originally breed for work, this double purpose is to face extreme variations in the temperature of the cow, its fertility, its reproduction, its milk (even if it was necessary to give milk for the presence of calf, and its meat). Was th...

What is the Full Form of LPG?

-
LPG Full Name is  Liquefied Petroleum Gas.   It is a flammable mixture of hydrocarbon gases used as a fuel in heating appliances and vehicles,  a clean and efficient source of energy having wide range of applications. It is a flammable mixture of hydrocarbon gases including Propane and Butane. It is extracted from crude oil and natural gas, and thus a non-renewable source of energy. Cooking- LPG has a very wide of uses and commonly used cooking fuel in several countries. It is especially used  by the central Government. It was once a popular fuel. Its supply has now reduced with the increased use of town gas. LPG is a popularly used cooking fuel.  In the safety font LPG cylinders must be updated to new standards in safety and user experience, giving a huge contribution for domestic usage. Uses of Liquefied Petroleum Gas (LPG) Motor Fuel -This is also used in the engine. It seems less than the cost of other fuels. LPG is used for internal combustion en...

What is the Full Form of TFT?

-
TFT Full Name is Thin Film Transistor. This is a special field-effect transistor. The thin film of dielectric layers and metal contact with an active semiconductor layer on the substrate. There is a normal substrate glass, because the primary application of TFT is in liquid crystal display. It is different from conventional transistor, where semiconductor material is usually substrate, such as silicon wafer. The use of liquid crystal displays is a direct-driven image element with the same simple display in the calculator and other devices, and therefore, the voltage of only one segment of these types of displays can be easily applied. This would be impractical for a bigger display, because it will have a lot of pixels, and in this way for each of the three colors, to avoid this, millions of connections per pixel (red, green and blue) need a problem Yes, the pixels should be known in rows and columns, which will reduce the number of connections from thousands to thousands. Co...
